Abstract: Equilibrium gas solubility and volumetric mass transfer coefficient of hydrogen in turpentine were measured at various pressures(2.0~8.0MPa),temperatures(353~473K), and 600 r·min-1 stirrer speeds in a high-pressure agitated autoclave (type FYX-2G).The result showed that equilibrium gas solubility and volumetric mass transfer coefficient of hydrogen increased with increasing temperature and pressure at a temperature range from 353K to 443K,and the solubility of hydrogen accorded with Henry Law,but at temperature 473K the solubility of hydrogen decreased.Based on the equation of solubility coefficient suggested by Vuuren, the relationship of gas equilibrium solubility with temperature and dissolution heat of hydrogen in turpentine were obtained.The model for volumetric mass transfer coefficient was also established.
